Abstract
Five new species of Taraxacum from northern Europe
(T. freticola, T. leptoscelum, T. nigrescens, T. opertum,
and T. palmgrenii) are validly named, described and
discussed, and their known distribution is presented. All are members
of T. sect. Ruderalia. For two
species known by illegitimate names (later homonyms), new names are
proposed: T. homoschistum, T. longiconicum.
Key words: Compositae, dandelions,
